However, the creep fracture of medium strength match joint, located in the low strength base metal remote from the weld interface, showed a ductile fracture character.
中强匹配接头蠕变断裂位置在远离焊缝界面的低强度母材区，呈延性断裂性质。
However, the interfacial failure tendency of low match welded joint is less man those of medium and high match welded joint.
